Abstract We present CO( J = 1–0) multiline observations toward the L914 dark cloud in vicinity of Cygnus X region, using 13.7 m millimeter telescope Purple Mountain Observatory. The CO reveal a long filament with an angular length ∼3.°6, corresponding to approximately 50 pc at measured distance ∼ 760 pc. Furthermore, group hair-like striations are discovered two subregions cloud, which connected dense ridge filament. These display quasiperiodic characteristics both intensity images and...
Artificial microbial ecosystems have been increasingly used to understand principles of ecology. These systems offer unique capabilities mimic a variety ecological interactions that otherwise would be difficult study experimentally in reasonable period time. However, the elucidation genetic bases for these remains daunting challenge. To address this issue, we designed and analysed synthetic symbiotic ecosystem which nature is defined explicitly. A mathematical model gene regulatory network...
We present the survey of $^{12}$CO/$^{13}$CO/C$^{18}$O (J=1-0) toward California Molecular Cloud (CMC) within region 161.75$^{\circ} \leqslant l \leqslant$ 167.75$^{\circ}$,-9.5$^{\circ} b $-7.5$^{\circ}$, using Purple Mountain Observatory (PMO) 13.7 m millimeter telescope. Adopting a distance 470 pc, mass observed molecular cloud estimated from $^{12}$CO, $^{13}$CO, and C$^{18}$O is about 2.59$\times$10$^{4}$ M$_\odot$, 0.85$\times$10$^{4}$ 0.09$\times$10$^{4}$ respectively. A large-scale...

Abstract We perform a comprehensive CO study toward the Monoceros OB1 (Mon OB1) region based on Milky Way Imaging Scroll Painting survey at an angular resolution of about 50″. The high-sensitivity data, together with high dynamic range, show that molecular gas in 8° × 4° displays complicated hierarchical structures and various morphology (e.g., filamentary, cavity-like, shell-like, other irregular structures). Based Gaussian decomposition clustering for 13 total 263 are identified whole...
